Breast cancer is the most common malignancy in women and the second leading cause of cancer death, exceeded only by lung cancer in 1985. One woman in eight who lives to age 85 will develop breast cancer at some time during her life.
At present there are over 2 million women living in the United States who have been treated for breast cancer. About 41,000 women will die from the disease. The chance of dying from breast cancer is about 1 in 33. However, the rate of death from breast cancer is going down. This decline is probably the result of early detection and improved treatment.
